The ministry confirmed the new detail of the talks, which will take place at an unnamed location in Sweden, after several media previously reported Lee’s involvement.

“He is in Sweden to participate in roundtable discussions in a lesser format with international experts, organised by the Swedish government and Sipri [Stockholm International Peace Research Institute, ed.],” Swedish foreign ministry press spokesperson Buster Mirow Emitslöf said.

Lee will participate as the South Korean representative on security questions relating to the Korean peninsula. The presence in Sweden of United States Special Representative for North Korea Stephen Biegun and Choe Son Hui, a North Korean vice-minister of foreign affairs, has already been confirmed.

Issues addressed by the talks will include the upcoming summit between US president Donald Trump and North Korean leader Kim Jong-Un.

The meeting will take place in a secret location, but police on Saturday blocked access to a conference facility at Mälaren northwest of Stockholm. Swedish media including tabloids Aftonbladet and Expressen reported that Swedish former Deputy Secretary-General of the United Nations Jan Eliasson was at the location.

The Ministry for Foreign Affairs would not confirm whether this would be the venue for the meetings and remained tight-lipped around the exact arrangements.

Sipri confirmed that it was involved in organizing the meeting and that it was taking place, but made no further comment.

“It is too early” to say anything, Sipri’s head of communications Stephanie Blenckner said.

On Friday, the White House announced that the US and North Korea had agreed to a second summit between Trump and Kim at the end of February. The location for that meeting has not been confirmed.

The two leaders first met in Singapore in June 2018.
